MORE than 50 people were queued outside the COVID-19 testing clinic at Redland Hospital on Monday as Sydney's northern beaches cluster grew by 15.
Residents were lined-up wearing masks, with some people reporting waiting times up to an hour and a half.
More than 16,350 tests have been performed across the state in just four days, an increase of 66 per cent on earlier in the month.
Border checkpoints are being rolled-out across the state again as restrictions come back into play for travellers from parts of NSW.
People entering the state from Greater Sydney as of 1am tomorrow will be forced into hotel quarantine.
The northern beaches cluster now stands at 83, with 15 new cases reported overnight.
The long queues for testing at Redland Hospital also comes a day after traces of the virus were found in wastewater at Cleveland.
Queensland's Chief Health Officer Jeannette Young said any wastewater detections highlight the importance of getting tested if people had symptoms of COVID-19.
No referral or booking is required at the Redland fever clinic, which is open from 8am to 4pm on weekdays and 8am to 2pm on weekends.
People must isolate while awaiting test results.
Dr Young said there may be a wait at some testing clinics, but there was a focus on testing people with symptoms as quickly as possible.
"I understand this is another big ask in a year of sacrifices, but I remind Queenslanders we have various testing facilities right across the state, not just in our major hospitals," Dr Young said.
"Thank you for your patience and understanding and please remember to social distance while you wait.
"If a testing site is experiencing high demand when you arrive, consider choosing another location."
